"Our universe is perfectly tailored for life. That may be the work of God or the result of our universe being one of many." (Emphasis mine.) So says the slug of a very readable article by Tim Folger published yesterday in the on-line version of Discover magazine: Science's Alternative to an Intelligent Creator: the Multiverse Theory.
The slug is wrong about one thing: It's not an either-or proposition. Even if multiple universes have been created, and ours is the one we happen to live in, we're still left with the question: How did that come to pass? (So says the Rev. Dr. John Polkinghorne, quoted in the Folger article, in one of his books.)
There's no reason to think a Creator would not create multiple universes instead of just one. That would be roughly parallel with the way we think evolution works in our particular universe: Lots of 'experiments,' with the ones that work, continuing on.
Or as Paul says in 1 Thess. 5.20: Don't scorn people who come up with novel ideas; instead, test everything, and keep that which seems good.
